Thermochromic glass

Abstract

The invention discloses thermochromic glass. The thermochromic glass comprises anti-scratching film layers, protective glass layers, a thermochromic layer, arc-shaped rims, filling grooves, adhesion layers and shading gratings, wherein the thermochromic layer is designed in a center layer of the thermochromic glass, the protective glass layers are adhered to the upper and lower surfaces of the thermochromic layer, the anti-scratching film layers are adhered to the outer end surfaces of the protective glass layers, and the arc-shaped rims are designed at the outer ends of the left and right sides of the thermochromic glass and are filled with the adhesion layers. The thermochromic layer of the thermochromic glass is prepared by the steps of adding a small amount of silver sulfide into sodium aluminum borate glass as a photosensitizer, adding a trace amount of copper and cadmium ions as a sensitizer, preparing glass through fusion, carrying out thermal treatment at a proper amount to accumulate silver sulfide into particles; and the thermochromic layer is capable of effectively absorbing thermal radiation or long wave light, and light transmitting the thermochromic layer under burning sun becomes soft, shady and cool, so that the light blocking and absorbing capacities of glass are enhanced, and the hardness and the strength are enhanced.

Description

technical field [0001] The invention relates to the technical field of glass production and manufacturing, in particular to a color-changing glass. Background technique [0002] In modern life, glass is widely used as a light-transmitting material. In order to block the wind and rain without blocking the line of sight, technicians in the field have developed a variety of glasses, such as sound-proof glass, tempered glass, etc., which greatly Improve the performance of glass used in various fields. [0003] For example, in the field of automotive glass applications, when the car is exposed to the hot sun, the sun irradiates the interior space of the car body and the seat cushion, causing its temperature to rise rapidly, which eventually makes it impossible for people to enter the car; The strong light encountered will also interfere with the driver's sight through the car glass, affecting the driver's normal driving and causing safety hazards. But car window adopts a kind o...

Problems solved by technology

[0003] For example, in the field of automotive glass applications, when the car is exposed to the hot sun, the sun irradiates the interior space of the car body and the seat cushion, causing its temperature to rise rapidly, eventually making it impossible for people to enter the car; the glare of the sun during the day or when driving at night The strong light encountered will also interfere with the driver's sight through the car glass, affecting the driver's normal driving and causing safety hazards

But car window adopts a kind of fixed film to block the strong light outside car window at present, after strong light disappears, the car window that adopts fixed film will continue to block light, and the light inside the car body becomes too dim, and cannot Realizing self-regulation, on the contrary, will hinder the normal observation of the driver, and such a fixed film will bring inconvenience to people
